Several plasma state transitions are found in the chromosphere. Indeed, the plasma can be partially or fully ionized, weakly or strongly magnetized, weakly or strongly collisional, all depending on the region considered [1]}, [2]}, [3]}. Furthermore, the solar atmosphere is a complex environment composed of many species with a large range of ionization levels. In partially ionized plasmas, charged species interact with other charged and neutral particles through collisions. Recent studies have suggested that ion-neutral interaction effects play an important role in the dynamics of the low solar atmosphere and its energy balance [4]}, [5]}, [6]}. Recent observations show that many dynamic and heating events, including through episodic magnetic reconnection, occur at chromospheric and transition region heights [7]}, [8]}, [9]}, [10]}, [11]}.
